Brake and Clutch pedal "Thump"

Posted by jwblazek On 2020/1/8 13:30:10

After 3 months of work, my Packard is back on the road after a total engine rebuild.

Engine is significantly more powerful and smooth, not to mention quiet! I actually use the rare factory glovebox door mounted tachometer when I come to a light as the engine is so smooth and quiet, I think it died!

And a big side benny, I can and will have the hood open at the next car shows to show off the majestic engine bay, something my late Dad always wanted to do with this car.

Now that all is so quiet, a noise I had prior to the rebuild, is a resounding THUMP from the brake or clutch pedal if you let them pop up by themselves. I do not see any "shock absorber" material or bumper that could stop that. Only thing close is what I refer to as the pedal shaft bellow seals, of which the durometer is so soft I do not see them doing anything except keeping the outside out

Suggestions ?
